2 Claims.

My invention relates to constructional features adapted for use with an attachment to the jaws of vises by which different types of articles or objects on which work is to be done may be readily secured to such attachments. My invention is illustrated mainly as applied to machinists devices but it is to be understood that the various jaw attachments and the clamping means for the articles of the so-called work to be manipulated may be applied to a large range of other types of Vises.

Many Vises are made have the ordinary and conventional gripping jaws in which objects to be operated upon are clamped between such jaws and in addition one or more sets of auxiliary jaws are mounted as part of the permanent equi ment of the vise, many of these being of the character of pipe gripping jaws and the like, however, these additional jaws complicate the construction of a vise making them more expensive and also inconvenient for handling a large run of work. Hence by far the large majority of Vises especially the machinists type, are of the simple type having a single pair of jaws, one jaw being attached to a fixed structure securable to a work bench or the like and the other jaw being on a movable member which may be adjusted to and from the fixed jaw and hence clamp articles or tools between the two jaws.

A main object and feature of my invention is without materially or radically changing the present jaw construction as used in a large number of Vises of the machinists type, I may accommodate these to handle various articles on which work is to be done or tools to be held between the vise jaws, thus by using my attachments with the various clamps, I may handle a large number of articles and tools which now require the use of special additional jaws of vise. For instance, my various jaw attachments and article clamps may grip such articles as rough pipes, finished round work in Which the surface must be protected from damage, screw threaded articles, etc. Further, by my invention the article clamps may be rotatable relative to the jaws of the vise and hence position the article or tools in the most convenient position for operationscarried on by the workmen. Therefore a main characteristic of my invention is the incorporation with the pair of jaws of a vise of jaw attachments with work clamps mounted to swivel or rotate on axes transverse to the face of the vise jaws. For sake of convenience and as usually a construction of various implements whereby used, the face of the vise jaws are usually vertical or substantially so, therefore by my invention the auxiliary jaws and clamps for the work may be considered as rotating on a horizontal axis.

In view of the fact that Vises particularly of the machinists type are made with jaws extending through a large range of size and also configuration, it is necessary to have the attachments so constructed as various ranges of size and contour and shape of the jaws, hence in one form of my invention I form complementary pairs of socket recesses in the faces of the opposing vise jaws. There may be one or more pairs of these recesses to accommodate different positions of the swivel jaw attachments. My invention further includes the jaw attachments or work clamps having a pivoting or swivel connection with the sockets of the vise jaws. These are made in such a manner that the attachments and work clamps are gripped and'thus restrained from accidental dislodgment from the faces of the vise jaws. A feature of this detail is, employing swivel pintles of an expanding type such as split resilient material tubes, the splits running longitudinally so that the tubes may be slightly compressed or reduced in diameter for fitting either in the sockets of the jaws or in corresponding apertures in the jaw attachment or work clamp. The expansion action then retains the jaw attachments or work clamps on the face of the vise jaws with their rotational mounting so that the articles or work gripped may be rotated on the horizontal axis above designated. 7

My invention also comprehends another means of attaching the work clamps to vise jaws, for instance by using face plates which are removably attached to the vise jaws. In one construction the vise jaws may have a series of vertical recesses positioned along the upper side of the jaws in contradistinction to the sockets on the face of the jaws, then an angular face plate having a vertical face to engage the vertical face of the vise jaw and a laterally extending arm is attached to the vise jaw by a pin extending into the recesses on the top of the vise jaw. These pinsare preferably of an expansible type formed of a longitudinally split tube and the arm is either shaped or bendable to conform to the curvature of the particular jaw of the vise with which it is to be used. Hence by this construction each of the jaws is provided with a removable face plate and the tool clamps are rotatably and preferably removably connected to the face plate, thus having the tool clamps rotate on axes at right angles to the face of the vise jaws.

stresses on a pipe or My invention comprehends further a face plate slidably mounted on the vise jaws by being made in the form of a dove-tailed channel with flanges engaging the upper and lower edges of the jaws of the vise. In such case the jaws are under-cut to accommodate the dove-tail shape of the channel. Such channels are therefore slipped into place from one end-of the vise jaws and to the face plates of the channels are attached various types of clamps for the work mounted in a rotational manner preferably by expansible pins engaging in complementary recesses or sockets, thus providing the rotational mounting transverse to the face of the vise jaws. As a modification of the dove-tail channel face plate attachment to the vise jaws and to accommodate-such construction without making the corresponding under-cut of the vise jaws I provide an auxiliary support which may be fitted over the top of the vise jaws and have an auxiliary face plate, this beingsecured by set screws or the like extending through end plates, then the auxiliary face plate has undercut edges engaging the upper and lower flangesofa :face plate channel. The particular article clamps then being rotationally mounted on the channel face plate.

Myinvention also includes the construction of readily .fitted .face plates which may be considered as having a flexible arm to extend over the top of a vise jaw, such arm being made of a flexible belt having weights attached thereto as by rivets. Such weights are sufficient to hold the face plate on a vise jaw and also to support the clamps for the various articles or work to be held in the vise. these-special clamps being rotatable on the face plates by the pin and socket connections.

Manifestly with the use of the vise jaws to support the article or work clamps or when such clamps are attached to a is necessary to provide a considerable variety of such clamps, therefore :my invention includes these clamps as having certain characteristics such as being'provided with a pivotal mounting by whichthe clamps may be rotated either directly on the face of the vise jaws or onthe face plates, such construction being developed through complementary sockets and preferably expansible tubular pins the article clamps are connected to the removable face plates by riveted pivots.

Certain of the work clamps of my invention have definite characteristics as for instance a clamp designed for round work having 'a finished surface in which a half circle jaw is provided. with grooves on the back allowing'a slight expansion to fit the round finished surface of the particular article and thus between two compleinentaryjawsto firmlyhold round workwhich has a finished surface that is not marred by such type removable face plate, it

however in some cases of jawface. Another construction includes-a split threaded jaw assembly in which when the two jaws or clamps are held-in place "by the visejaws the threaded end of a pipe maybe threaded into such jaws and extend downwardly to a removable end bar. This forms an abutment giving a firm resistance to the threading or other torque threaded bar. The loosening of the end bar and opening of the vise jaws thus permits ready removal of the article gripped by such threaded clamps or jaws.

Fig. 18 is an elevation taken in the direction of the arrow l8 ofFig. 17.

Fig. 19 is a plan taken in the direction of the arrow IQ of Fig. 17 but illustrating two jaw assemblies.

Referring first to the construction of Figs. 1 through '7, in Fig. 1 there is illustrated a machinists vise H which has'the characteristics of a fixed jaw l2 and a movable jaw 13. Each of these jaws is similar and each jaw has a jaw face indicated at I4. 'In the particular construction of the jaw attachments illustrated in connection with Fig. 1, the complementary jaw faces each have socket recesses l5 of which there are three shown to position the attachments in different locations. These recesses are preferably made by drilling cylindrical holes in the face of the vise jaws and asthe vice jaws are frequently separate renewable metal elements, these can be made during the period of manufacture before the vise jawsare hardened. The purpose of the recesses is to accommodate pintle pins designated 20, note Fig. 6. These are preferably similar for a large variety of jaw attachments being constructed of a tube 2| with longitudinal splits 22. One type of a jaw attachmentdesigned for gripping round by the numeral 25. This has a bore 26 with a split pintle 20 fitted therein. The attachment has a flat rear face 21 to fit flat against the face I 4 of the vise jaw, with the pintle fitted in the recess I and being held by the expansion action of the split pintle. It is therefore apparent that the attachment for holding the work may be secured in any one of the sockets I 5 and rotatable thus on a horizontal axis. Complementary attachments are secured in diametrically opposite sockets. In the particular illustration the work gripping face 28 is illustrated as a substantially half cylinder extending transversely across the jaw attachment or work clamping tool. This is to grip round articles such as shown in Fig. 1 in which care must be taken not to mar the surface, therefore the semicylindrical face 28 must be of the proper radius. In order to facilitate turning the work clamp at various angles, the periphery 29 is a cylinder and Where it is necessary to decrease the radius of the work engaging faces 28, this is done by an insert jaw attachment 35 which has an outer cylindrical shaped face complementary to that of the curve 28 36 designed for the a face plate 4| to fit snugly against the face of the jaw and is provided with a curved arm 42 at the top either shaped or bendable to engage the upper surface of the vise jaw. This arm is provided with a split pin 43 which may engage in any one of a series of vertical sockets or recesses 44 on the upper face of the vise jaw, these rece'sses being parallel to the face of the jaw; By this construction the complete pairs of face plates are readily attached to the opposite sockets 44 and then may be used for a variety of work gripping tools attached thereto.

For instance, I illustrate in Figs. 8, 9 and one form of work gripping auxiliary jaws designated 50. These have a pintle connection 52 which as a type of rivet mounting the attachmenton the face plate 4| in such a manner that it may rotate. The attachment is provided with as i1- lustrated, converging V type of surfaces 53 and is shown as having a cylindrical periphery 54. By this construction it will be seen that with the pairs of jaws a considerable variety of work may be attached to the particular jaw attachment and any one of these jaw attachments may be readily mounted on vise jaws by means of the face plate and arm support as designated by the numeral 40.

In the construction of Figs. 11, 12 and 13, the vise jaws indicated at 60 are modified by having a rectly in the face of the vise jaws and may be utilized in a similar manner to the face plate 4| to grip round work of a v certain size, I utilize the supplementary jaws 15. This has sur faces 16 complementary to the surface 12, the outer surface 71 is substantially a semi-circle, the split pintle 18 isutilized for attachment in the hollow pintle 1| and extending from the back face there are notches 79 running the length of the supplementary jaw. This allows fora slight spreading to accommodate the article gripped between a pair of the supplementary jaws. There is sufiicient yield at the notches 19 to accomplish such purpose. It is manifest therefore that these notches may be utilized on any type of jaw where it is desired to have a slight distortion.

In'Figs. 14, 15 and 16 I illustrate a further form of the dove-tail connection of the jaw attachments as the undercut vise jaws such as 60 should be made during the manufacture of the vise, it being somewhat expensive to form the undercut groove 6| in a finished vise, therefore I utilize a face plate holder 80 which has a face plate IN to feed against the face of the vise jaw I2. This has a top sembly has a face plate 9| lower flanges 92 type of channel this face plate assembly may either of the ends 82 for mounting any type jaws.

The same type of be inserted from or 83 and may be utilized of the auxiliary clamps o face plate channel assemblies of the jaws of the vise. In

ed pipe is smooth surface.

, threads of the same plate I0'l;has.a socket recess in which any of the removable :auxiliary clamps :may be pivoted. Manifestly it is necessary to havetwo sets of the weighted and strapped, type of face plate assembly but as thethrust gripping work is, directly at'right angles'to the face of the vise jaws, these face plates are retained in accurate position although they are not fastened positively into thejaws of the-vise.

One of my types of work holders for a threadindicated inFigs. 17, 18 and l9 -and designated III]. This employs for each half section an auxiliary jaw block HI with the expandible pintle H2.- This has a semi-cylindrical gripping face H3 of which thelowerpart ll l is screw threaded and the upper part 'll5 has a An end bar H6 is attached to each jaw block by set screws l l'l. In the operation of this type of supplementary jaws, the two semi-circular parts edge to edge ;by the clamping action of .the two vise jaws, the two end bars having been snugly adjusted, then with this typea pipe or bar to be threaded or having .other work done thereon is threaded into the socket formed by the two halves of the-supplementary jaw assembly. For instance a pipe or bar may be threaded downwardly until itcomesto a positive stop against the two end bars H6, then the portion of the pipe or bar extending beyond the jaws maybe threaded or have other work done thereon. The end bar prevents the pipe or round bar from being threaded to a greater distance in the threaded jaws although in fact when forming direction of turn, tends to become more tightly gripped in the threaded jaws. In quickly releasing the pipeor other article from these jaws the vise jaws are moved apart and the end bars H6 slightly loosened by loosening the set screws II'I whence the pipe may be readily disengaged from the threaded jaws. The upper smooth surfaced portion H5 is preferably slightly greater in diameter than the lower screw threaded part 1 I4 thereby forming in effect a slight shoulder at the top of,

thethreads, hence when it is desired :to grip a long threaded work such as a pipe or a rod, the end bars IIB may be removed, the jaws moving together and the work holders aligned, then the long threaded article may be threaded in the work holders until it reaches the limit of the unthreaded part H5. This construction with long work extending beyond both ends of the work holders H0 prevents such article fromrotating when it is threaded or other work is done on it. Thisof course only applies when the turning or torque stresses as in threading would tend 7 in the faces of the jaw, the .pipe 535 threads I I4, therefore .to thread the article er clamps, however this is usually the case as tighter into the work holdstances in amacl'nne shop, For instance the two halves of the-clamp may be placed on a work bench and used tosupport the articles on which work is to .be done or for many other purposes in which: it is now customary to have special tools, therefore where it is desired to use the are aligned and clamped go workclamps for purposes other than as illusjaws, it is necessary trated attached to the vise that .a removable pintle be utilized instead of a rivet connection.

Various changes may be made in the details of. the [construction without departing from the spirit or scope of the invention as defined by the appended claims.
